The present invention relates to the technical field of air purification and compression, and particularly to a circulation boosting and ventilating air compressor.

BACKGROUND

The present axial flow fan in use has many disadvantages such as lower wind pressure, poor capability of handling pollution material, loud noise, larger energy consumption and inefficiency etc.; the present centrifugal axial-flow gas compressor also has the disadvantages of complex structure, more consumed materials, heaver weight, poor boosting effect, inefficiency, as well as larger energy consumption and narrow range of use.

DISCLOSURE OF THE INVENTION

The objective of the present invention is providing a circulation boosting and ventilating air compressor with the advantages of simplified structure, less consumed materials, light weight, powerful capability of handling pollution material, better boosting effect, efficiency, as well as less energy consumption and wide range of use.

The present invention is carried out by the following technical solution: a circulation boosting and ventilating air compressor which comprises a compressor shell and a rotor, and which is characterized in that: the rotor consists of a wind gear and a drive shaft; the wind gear consists of a shaft sleeve, a wind gear plate and wind teeth; the wind gear is connected with the drive shaft through the shaft sleeve; the wind teeth are connected with the wind gear plate through wind tooth roots and formed by overlying a plurality of layers of wind tooth blades; a wind tooth air passage is provided between two adjacent wind tooth blades and has a wind tooth air passage inlet and a wind tooth air passage outlet.

The circulation boosting and ventilating air compressor provided in the present invention is entirely different from the present old-type axial flow fan and the centrifugal axial-flow gas compressor in terms of configuration and elements. For convenient narrative and clear expression, there are several terminologies need to be explained as follows:

The side wall and the side surface of the rotor and the compressor body to which the rotor axis points are called an axial side wall and an axial side surface of ventilation compressor. An axial windward side (an axial air inlet side) of the wind gear is determined to be an axial external side (or a front axial side) of wind gear, and another side of the wind gear corresponding the axial external side is determined to be an internal side (or a rear axial side) of wind gear.

A portion of the wind tooth blade radial close to the wind gear plate is a root of the wind tooth blade, which is called a tooth root for short; a radial end of the wind tooth blade is a wind tooth top, which is called a tooth top for short; a portion of the wind tooth close to the tooth root is called a lower portion or a bottom of wind tooth; a portion of the wind tooth close to the tooth top is called an upper portion of wind tooth; an axial air inlet edge of the wind tooth is called a front edge of wind tooth; an axial air outlet edge of the wind tooth is called a rear edge of wind tooth.

A front and back of wind tooth: a forward rotating airflow points to the front of wind tooth; a backward rotating airflow points to the back of wind tooth.

A top circle of the wind gear is a radial edge of wind gear; an axial side edge of the wind gear is an axial edge of wind gear, which is divided into a front axial edge of wind tooth and a rear axial edge of wind tooth.

The main structure part of the circulation boosting and ventilating air compressor is the wind gear on the rotor, and this ventilating air compressor can produce high-pressure axis airflow merely by the wind gear, without using a cylinder-shaped shell and axial static flow deflectors in front and back.

The wind gear consists of a shaft sleeve, a wind gear plate and wind teeth, wherein the wind gear plate is generally similar to the core tubes of the old-type axial flow fan and axial-flow gas compressor, and the wind teeth are connected onto the wind gear plate.

A plurality of wind teeth are connected onto the wind gear plate, each of the wind teeth is formed by overlying a plurality of layers of wind tooth blades, each of the wind teeth has the equal amount of wind tooth blades, and the corresponding wind tooth blades have the same shapes and sizes. A wind tooth air passage is provided between the layers of wind tooth blades, the overlying wind tooth blades have no two layers or several layers jointed together, and there is a certain gap between every two layers of wind tooth blades to facilitate passing of the airflow therebetween. The wind tooth air passage, that is, the spacing size between two layers of wind tooth blades shall be determined according to the requirements of usage.

A wind tooth air passage inlet is provided in a front edge of wind tooth, and a wind tooth air passage outlet is provided in a rear edge of wind tooth, that is, the airflow can enter the wind tooth air passage from an air inlet end of the front edge of wind tooth, and then outflow from an air outlet end of the rear edge of wind tooth.

Each of wind teeth has at least two layers of wind tooth blades, and has at least one layer of wind tooth air passage, for example: two layers of wind tooth blades constitute one layer of wind tooth air passage, three layers of wind tooth blades constitute two layers of wind tooth air passage, and four layers of wind tooth blades constitute three layers of wind tooth air passage etc.

When the wind teeth are in operation, the wind teeth take in air from not only the wind tooth air passage inlet at the air inlet end of the front edge of wind tooth but also the external working surface at the air inlet end of the front edge of wind tooth, that is, the wind teeth take in dual air. Therefore, the whole wind gear has a larger rate of flow, and more layers of wind tooth air passage result in more amount of air taken in by the wind teeth.

More important is that the gas entering the wind tooth air passage absorbs energy from the two layers of wind tooth blades, so as to obtain higher wind pressure.

This solution provides a leakproof separation plate on the wind tooth top, which has the following two objectives: (1) preventing gas in the wind tooth air passage outflow of the tooth top due to the centrifugal force; (2) connecting the blade tip of the wind tooth blade, which can not only reinforce the wind gear but also separate the wind tooth blades each other to form the wind tooth air passage in a fixed form. The leakproof separation plate should not be heavy, thus it preferably is made of thin plates.

In this solution, the wind tooth root may further be provided with a tooth root support separation plate which is connected to the root of the wind tooth blade.

In this solution, the wind tooth air passage may further be provided with a pressurization flow deflector therein, the purpose of which is making the airflow inside the wind tooth air passage flow through the wind tooth air passage along the track determined by the pressurization flow deflector. In this case, the airflow flowing through the wind tooth air passage can absorb energy from not only double walls of the wind teeth but also the pressurization flow deflector, thereby obtaining a higher wind pressure. The pressurization flow deflector must run through the wind tooth air passage by the wind tooth air passage inlet of the front edge of wind tooth (or nearby the wind tooth air passage inlet), and such a running-through may be straightforward, or slanting, or linear or curved. The pressurization flow deflector has a longitudinal edge connected to a side wall of the wind tooth air passage. According to the requirements, each wind tooth air passage may provided with one line of pressurization flow deflector, or more than two lines of pressurization flow deflector; the pressurization flow deflector can make the wind gear obtain the boosting effect and achieve the noise-reducing effect. The pressurization flow deflector may have many different kinds of structure forms, such as a candybar, a curved plate, and a wing shape etc.; the pressurization flow deflector has a length which may be greater or less than a width (a distance from the front edge of wind tooth to the rear edge of wind tooth) of the wind tooth air passage, or which may be equal to the width of the wind tooth air passage.

To ensure the wind gear having a sufficient intensity and rigidity, this technical solution may further comprise a reinforcing rib provided on the wind gear, and the reinforcing rib is positioned on an axial side of the wind gear; the wind teeth of the wind gear are integrated as a whole in virtue of the reinforcing rib, so as to make the whole wind gear have a better intensity and rigidity.

In this technical solution, for increasing the wind pressure more effectively, the wind tooth air passage outlet of the previous wind tooth faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the next layer, so that the airflow exhausted from the wind tooth air passage outlet of the previous wind tooth enters the wind tooth air passage of the adjacent wind tooth followed in the next layer to be processed and pressurized.

The whole wind gear with more layers of wind tooth blades shall result in more layers of wind tooth air passages; and in the case where relevant wind tooth air passage outlets face to the adjacent wind tooth air passage inlets, the airflow entering the wind gear will get more times of being pressurized, so that the wind pressure thereof is increased more greatly, For example, if the wind gear has two layers of wind tooth air passage, the airflow entering the wind gear will get two times of being pressurized; if the wind gear has three layers of wind tooth air passage, the airflow entering the wind gear will get three times of being pressurized etc., that is to say, the gas taken in from the external working surface of wind tooth and the wind tooth air passage inlet can pass through the multi-layered wind tooth air passages to be processed and pressurized by many times, therefore, the ventilating air compressor can obtain a very high wind pressure.

The wind tooth air passage outlet of the wind gear faces to the wind tooth air passage inlet of the adjacent wind tooth followed, if the wind tooth air passage inlet and the wind tooth air passage outlet are corresponding to each other in the same layer, for instance, the wind tooth air passage outlet of the previous wind tooth in the first layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the first layer, the wind tooth air passage outlet of the previous wind tooth in the second layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the second layer . . . , such a structure can not make the gear discharge airflow outside, that is, the wind gear can not work normally, thereby it can not achieve the purpose of being pressurized by multi-time.

In order to make the wind gear achieve the purpose of being pressurized by multi-time, the wind tooth air passage inlet and the wind tooth air passage outlet must be corresponding to each other in different layers, for instance, the wind tooth air passage outlet of the previous wind tooth in the first layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the second layer, the wind tooth air passage outlet of the previous wind tooth in the second layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the third layer . . . etc.

As for the wind tooth air passage inlet and the wind tooth air passage outlet which are corresponding to each other in different layers, there are many different kinds of structural methods, for instance, a rear edge outlet of the external working surface of the previous wind tooth faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the first layer, the wind tooth air passage outlet of the previous wind tooth in the first layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the second layer, the wind tooth air passage outlet of the previous wind tooth in the second layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the third layer . . . ; and for instance, a rear edge outlet of the external working surface of the previous wind tooth and the wind tooth air passage outlet thereof in the first layer face to the wind tooth air passage inlet of the adjacent wind tooth followed in the second layer, the wind tooth air passage outlet of the previous wind tooth in the second layer faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the third layer . . . ; and for instance, the wind tooth air passage outlets of the previous wind tooth in the first and second layers face to the wind tooth air passage inlets of the adjacent wind teeth followed in the third and fourth layers, the wind tooth air passage outlets of the previous wind tooth in the third and fourth layer face to the wind tooth air passage inlets of the adjacent wind teeth followed in the fifth and sixth layers . . . etc. In a word, there are many different kinds of structural methods for the wind tooth air passage inlet and the wind tooth air passage outlet which are corresponding to each other in different layers. And the specific structural method shall be determined by the specific requirements of usage and how many layers of the wind tooth air passages.

The wind gear has many methods of taking in air, for example, air is taken in from the external working surface at the air inlet end of the front edge of wind tooth, or from one wind tooth air passage inlet, or two/three wind tooth air passage inlets; air is taken in from the external working surface at the air inlet end when from one wind tooth air passage inlet, or two/three wind tooth air passage inlets . . . etc.

The wind gear also has many methods of exhausting air, for example, air is exhausted from the external working surface at the air outlet end of the rear edge of wind tooth, or air is exhausted from the external working surface at the air outlet end of the rear edge of wind tooth when from one wind tooth air passage outlet, or several wind tooth air passage inlets . . . etc. The direction of exhausting air may be tangential to the rotor, or be axial.

The wind teeth of the wind gear consist of the multi-layered wind tooth blades, and the wind tooth air passages thereof are also multi-layered. The wind tooth air passage outlet of the previous wind tooth faces to the wind tooth air passage inlet of the adjacent wind tooth followed in the different layer, thus the wind tooth air passage inlet of the wind tooth in the first layer is the effective air inlet of the wind tooth, and the airflow inlet direction is similar to the rotary track of the rotor; the wind tooth air passage outlet of the wind tooth in the last layer is the effective air outlet of the wind tooth, and the airflow outlet direction may be tangential to the rotor, or be axial to the rotor; the wind tooth air passage inlets of the wind teeth in the second, third . . . layers are the transitional air inlets, and the inlet direction needs to be corresponding to the wind tooth air passage outlets of the adjacent wind teeth advanced in the first, second, third . . . layers; and the wind tooth air passage outlets of the wind teeth in the first, second, third . . . layers are the transitional air outlets, and the outlet direction needs to be corresponding to the wind tooth air passage inlets of the adjacent wind teeth followed in the second, third and fourth layers.

in this technical solution, the wind teeth are formed by overlying a plurality of layers of wind tooth blades; the wind tooth air passage is structured in multi-layer, and the wind tooth air passage inlet and outlet are corresponding to each other in different layers, so that the gas taken in by the wind tooth air passage is processed and pressurized in several times, more than ten times and dozens of times along with one revolution of the rotor; and since the gas in the wind tooth air passage can absorb energy from the double walls of the wind tooth blades to increase pressure, the effective wind tooth air passage outlet in the last layer exhausts the gas with a very high pressure. If the gas is processed by an old-typed centrifugal or axial-flow gas compressor, it must adopt single-stage impellers of several stages, more than ten stages and dozens of ten stages classes in series to have the gas taken in by the front end of the compressor processed and pressurized in several times, more than ten times and dozens of times; moreover, static rectifying and deflecting devices must be provided between the single-stage impellers so as to have the gas taken in by the gas compressor processed and pressurized in several times, more than ten times and dozens of times.

As compared with the present old-type axial flow or centrifugal gas compressor, the structure of the air compressor in the present invention is simplified, and the material cost, weight and friction of the air compressor are greatly reduced. Therefore, the efficiency and energy consumption of the air compressor are improved, and the air compressor is convenient to transport, install, use and maintain, as well as having a wide range of usage.

The present invention provides a circulation boosting and ventilating air compressor, wherein the wind tooth air passage outlet of the previous wind tooth communicates the wind tooth air passage of the adjacent wind tooth followed by means of a wind tooth air passage communicating vessel, in this case, the wind tooth air passage of the previous wind tooth and the wind tooth air passage of the followed wind tooth form a uniform wind tooth air passage. For instance, the wind tooth air passage outlet of the previous wind tooth in the first layer communicates the wind tooth air passage inlet of the adjacent wind tooth followed in the second layer, then the wind tooth air passage inlet of the previous wind tooth in the first layer becomes the uniform wind tooth air passage inlet, and the wind tooth air passage outlet of the followed wind tooth in the second layer becomes the uniform wind tooth air passage outlet. If from the front to the back, the wind tooth air passage outlet of the previous wind tooth A in the first layer communicates the wind tooth air passage inlet of the adjacent wind tooth B followed in the second layer, and the wind tooth air passage outlet of the previous wind tooth B in the second layer communicates the wind tooth air passage inlet of the adjacent wind tooth C followed in the third layer; in this case, the wind tooth air passage , outlet of the previous wind tooth C in the third layer communicates the wind tooth air passage inlet of the adjacent wind tooth D followed in the fourth layer, so as to form the uniform wind tooth air passage, then the wind tooth air passage inlet of the previous wind tooth A in the first layer becomes the uniform wind tooth air passage inlet, and the wind tooth air passage outlet of the wind tooth D followed in the fourth layer becomes the uniform wind tooth air passage outlet.

For instance, the wind tooth air passage outlets and inlets of the wind teeth communicate each other to form the uniform wind tooth air passage, then the wind tooth air passage inlet of the previous wind tooth in the first layer becomes the uniform wind tooth air passage inlet, and the wind tooth air passage outlet of the fifth wind tooth in the fifth layer becomes the uniform wind tooth air passage outlet . . . , in a word, the connecting method of the wind tooth air passage inlet and outlet shall be determined according to the actual usage and the amount of layers of the wind tooth air passages.

The wind tooth air passage inlet and outlet communicate each other to form the uniform wind tooth air passage, which may be a ring or a circular arc; the airflow flows circularly in such a ring-shaped or arc-shaped air passage around the wind gear plate.

The wind tooth air passage communicating vessel is positioned between two wind teeth, and has an inside air passage which may be divided into be multi-layered, and the air passage in each layer communicates the corresponding wind tooth air passage of the previous and followed wind tooth respectively; the inside air passage may be the same cavity without being divided into be multi-layered, and the cavity may communicate the wind tooth air passage of the previous and followed wind tooth in different layers.

To further improve the pressurization effect and efficiency of the ventilating air compressor, the rotor may have several wind gears in series simultaneously, i.e. each wind tooth air passage outlet of the first wind gear corresponds or communicates each wind tooth air passage inlet of another or other corresponding wind gears, the several wind gears have their corresponding wind tooth air passages in series to form a uniform wind tooth air passage, the wind tooth air passage inlet of the first wind gear in each layer becomes the uniform wind tooth air passage inlet of the whole rotor with the wind gears in series, the wind tooth effective outlet (or axial or tangential) of the wind gear in the last class becomes the uniform wind tooth air passage outlet of the whole rotor with the wind gears in series. By such a structure, the gas, which enters the wind tooth air passage of the first-stage wind gear, can rotate several revolutions with the same rotor to be processed and pressurized by the multi-layered wind tooth air passage of the multi-staged wind gear, so as to obtain more energy and produce a higher wind pressure. The whole pressurization process is performed in the uniform wind tooth air passage of the same rotor in series, without any static deflecting devices.

As for the circulation boosting and ventilating air compressor, the wind tooth air passage inlet and outlet of the same wind gear in different layers are corresponding or communicate each other, or after the wind tooth air passage inlet and outlet of several wind gears communicate each other, and the wind gears in different layers or different wind gears in series form the uniform wind tooth air passage, the gas taken in by the external working surface at the air inlet end of wind tooth or the wind tooth air passage in the first layer can rotate one revolution or several revolutions along with the rotor to be processed by the multi-layered wind tooth air passages, so as to obtain more energy and produce a higher wind pressure. The whole pressurization process is performed in the wind gear of the same rotor, without any static deflecting devices. Thus, the circulation boosting and ventilating air compressor formed by the multi-staged wind gears in series can also simplify its structure greatly, reduce the material cost, weight and pneumatic friction area, save resources and energy significantly, and improve efficiency drastically.

As for the circulation boosting and ventilating air compressor in the present invention, the wind tooth air passage inlet direction forms a little crossing angle with the swing of the rotor (or it is substantially the same direction as the swing of the rotor). The wind tooth air passage may have many different kinds of structural forms such as longitudinal extending form, shrinking form and uniform section form etc. The inner diameter cross section of the wind tooth may be round, square, arc, and oblate etc. The wind tooth outlet may be axial or tangential.

The present invention adopts three kinds of pressurization working principles of processing gas, i.e. pressurization working principle by stamping force, pressurization working principle by rotating force and pressurization working principle by both stamping force and rotating force.

As for a low-pressure circulation boosting and ventilating air compressor, it may adopt the simple pressurization working principle by stamping force and the simple pressurization working principle by rotating force respectively. This kind of ventilating air compressor adopts the structural form of single-stage wind gear, it is unnecessary to have too many layers of the wind tooth blades and the wind tooth air passages, and the uniform wind tooth air passage after the wind tooth air passages communicate with each other shall not be too long, which is preferably less than or equal to the circumference of the rotor, or which is a circular arc occupying a part of the whole circumference. The wind gear outlet is axial (or tangential to the rotor). In such a structural form, if the wind tooth air passage inlet direction is contrary to the swing of the rotor, it shall adopt the simple pressurization working principle by stamping force. When the rotor is rotating, the gas rushes in the wind tooth air passage via the wind tooth air passage inlet contrary to the swing of the rotor; since the gas flows in a direction contrary to a moving direction of the side wall of the wind tooth air passage, the gas can absorb energy continually so as to be compressed and pressurized. In such a structural form, if the wind tooth air passage inlet direction is the same as the swing of the rotor, it shall adopt the simple pressurization working principle by rotating force. The wind tooth air passage extends longitudinally (or the wind tooth air passage extends by separation of the wind tooth air passage pressurization flow deflector); when the rotor is rotating, the front end of the wind tooth air passage inlet produces a kind of draft, which sucks the gas outside into the wind tooth air passage directly. Since the gas flows in the same direction as the moving direction of the side wall of the wind tooth air passage, the gas can absorb energy continually so as to be accelerated. And since the wind tooth air passage extends longitudinally, the gas can also be decelerated and diffused continually so as to obtain a higher wind pressure at last.

As for a high-pressure or super-high-pressure circulation boosting and ventilating air compressor, the present invention may adopt the simple pressurization working principle by rotating force and the pressurization working principle by both stamping force and rotating force respectively. The compressor preferably adopts the structural form of multi-layered wind tooth air passages of the single-stage multi-layered wind tooth blades or multi-staged wind gears in series, and adopts the single-ring wind tooth air passage with one revolution of flow, or the multi-ring wind tooth air passage with several revolutions of flow. The wind tooth air passage outlet may be tangential or axial; the ring-shaped wind tooth air passage may be in an extending form, a shrinking form, or a uniform section form.

In such a structural form, if a flow direction of the wind tooth air passage at the front of the rotor is contrary to the swing of the rotor, and a flow direction of the wind tooth air passage at the back of the rotor is the same as the swing of the rotor, it shall preferably adopt the pressurization working principle by both stamping force and rotating force. When the rotor is rotating, the gas rushes in the wind tooth air passage at the front of the rotor via the wind tooth air passage inlet at the front edge of the rotor contrary to the swing of the rotor; since the gas flows in a direction contrary to a moving direction of the side wall of the wind tooth air passage at the front of the rotor, the gas can absorb energy continually so as to be compressed and pressurized. After flowing through the wind tooth air passage at the front of the rotor, the gas flows into the wind tooth air passage at the back of the rotor directly after reversing, and flows in the same direction as the swing of the rotor, in this case, the gas obtains pressure energy by means of the rotating force. Since the gas in the wind tooth air passage at the back of the rotor flows in a direction same as the moving direction of the side wall of the wind tooth air passage and the pressurization flow deflector of the wind tooth air passage, the gas can absorb energy continually so as to be accelerated and pressurized.

As for the rotor with such a structural form, there are the following three kinds of technical measures of changing the flow direction of the gas in the wind tooth air passage at the front of the rotor, and making the gas enter the wind tooth air passage down-flow at the back of the rotor and flow complying with the swing of the rotor to absorb energy continually:

(1) connecting the wind tooth air passage outlet at the front of the rotor with the wind tooth air passage inlet at the back of the rotor via the wind tooth air passage communicating vessel; in this case, the gas from the wind tooth air passage outlet at the front of the rotor can be easily switched into the wind tooth air passage at the back of the rotor via the wind tooth air passage communicating vessel, so as to flow complying with the swing of the rotor;

(2) providing a reversing deflector (static or rotary) between the wind tooth air passage outlet at the front of the rotor and the wind tooth air passage inlet at the back of the rotor, so as to change the flow direction of the gas from the wind tooth air passage outlet at the front of the rotor by means of the reversing deflector;

(3) as for the rotor with multi-staged wind gears in series, it shall adopt the method of double-shaft in series, that is, to drive the wind gears at the front and back of the compressor body respectively by two concentric transmission shafts to rotate reversely; in this case, the gas in the wind tooth air passage at the front of the compressor body flows contrary to the swing of the wind gear, so as to obtain pressure energy by the stamping force, and the gas flowing into the wind tooth air passage at the back of the compressor body flows complying with the swing of the rotor, so as to obtain pressure energy by the rotating force.

The present invention provides the compressor used as a high-pressure or super-high-pressure air compressor. If the gas in each wind tooth air passage at the front and back of the rotor flows in the same direction as the swing of the rotor, and the wind tooth air passage inlet direction at the front of the rotor is also the same as the swing of the rotor, the rotor with such a structural form shall adopt the simple rotating force to process gas. When the rotor is rotating, it can produce a kind of negative pressure in the wind tooth air passage of the rotor as well as at the wind tooth air passage inlet, and the negative pressure can draw the gas outside into the wind tooth air passage directly. Since the flow direction of the gas is consistent with the moving direction of the side wall of the wind tooth air passage, the gas can obtain energy continually to be accelerated.

The above structural form can achieve a better effect in case of adding a fan or an after-flow fan impeller at the front end of the rotor to blast directly toward the wind tooth air passage inlet.

The rotor of the circulation boosting and ventilating air compressor in the present invention is driven by an electric motor, or a diesel engine, gasoline engine, a gas turbine, a steam turbine etc.

The circulation boosting and ventilating air compressor in the present invention has a wide range of usage. As a general ventilator, the circulation boosting and ventilating air compressor has a simplified structure, saving materials, light weight, high efficiency and saving energy, and can be applied to many ventilating and air-supplying situations. As a high-pressure or super-high-pressure air compressor, the circulation boosting and ventilating air compressor has more advantages due to its simplified structure, light weight, high efficiency and saving energy as compared with all kinds of centrifugal compressors, axial flow compressors, and roots blowers, thus the circulation boosting and ventilating air compressor is adapted to replace the all kinds of special compressors, especially the compressors used for various vehicles, ships and aircrafts like the airplane.

THE PREFERRED EMBODIMENTS FOR CARRYING OUT THE PRESENT INVENTION

Embodiment 1 (please refers to FIGS. 1-3), a circulation boosting and ventilating air compressor comprises a compressor shell 1, a rotor 2, a wind gear 3, a drive shaft 4, a shaft sleeve 5, a wind gear plate 6 and wind teeth 7, wherein the wind gear plate 6 is connected with the shaft sleeve 5; the wind teeth 7 are connected with the wind gear plate 6 through the wind tooth root 8; four wind teeth 7 are formed by overlying two layers of arc-shaped sheet iron wind tooth blades 9; a wind tooth air passage 10 is provided between the wind tooth blades 9; the wind tooth air passage 10 is provided with a wind tooth air passage inlet 11 and a wind tooth air passage outlet 12; a ring-shaped reinforcing rib 25 is provided on two axial sides of the wind gear 3; the ring-shaped reinforcing rib 25 is connected with each of the wind tooth blades 9 by welding; the wind gear plate 6 is in a shape of cylinder; the wind tooth root 8 is welded to the wind gear plate 6; the wind gear 3 is connected with the drive shaft 4 of the electric motor 24 through the shaft sleeve 5. The direction of the air inlet 21 at the front edge of wind tooth working surface and the direction of the wind tooth air passage inlet 11 form a litter crossing angle with the swing of the wind gear, the direction of the air outlet 22 at the rear edge of wind tooth working surface and the wind tooth air passage outlet direction 12 are axial.

The circulation boosting and ventilating air compressor adopts the simple pressurization working principle by stamping force; in the working period, the gas from the front axial side (on which the electric motor is provided) enters the external working surface of wind tooth and the wind tooth air passage 10 via the air inlet 21 at the front edge of wind tooth working surface and the wind tooth air passage inlet 11, and then is exhausted from the wind gear in an axial direction via the air outlet 22 at the rear edge of wind tooth working surface and the wind tooth air passage outlet 12. The amount of wind is large since the air is taken in via the air inlet 21 at the front edge of wind tooth working surface and the wind tooth air passage inlet 11; moreover, since the flow direction of the gas inside the wind tooth air passage is contrary to the moving direction of the wind tooth air passage 10, the gas can absorb energy continually to be compressed and pressurized, thereby the wind pressure thereof is higher.

In this embodiment 1, the intake air and the pressurization are duple; thereby the wind pressure and the amount of wind are higher and larger than those of the old-typed axial flow fan. The one-stage wind gear can compete the two-staged old-typed axial flow fan without adding any intermediate static deflecting devices due to its small volume, using less materials, high efficiency and energy saving.

In this embodiment 1, the circulation boosting and ventilating air compressor is adapted to be made into all kinds of axial flow fans for ventilating and air supplying.

In this embodiment 1, the circulation boosting and ventilating air compressor is adapted to be made into a ducted fan or blower, and can be made into a general ventilator in case of removing the compressor shell (merely adding a shield in outside of the rotor).

Embodiment 2 (please refers to FIGS. 4-6), the circulation boosting and ventilating air compressor is substantially the same as that in the embodiment 1. The first different point is: the wind teeth in the embodiment 2 are formed by overlying three layers of wind tooth blades; the wind tooth air passage 10 is two-layered, the wind tooth air passage outlet 12 of the previous wind tooth in the first layer is corresponding to the wind tooth air passage inlet 11 of the adjacent wind tooth followed in the second layer; as shown in FIGS. 4-5, the wind tooth air passage outlet 12 of the previous wind tooth in the first layer is a transitional air outlet, which is corresponding to the wind tooth air passage inlet 11 of the adjacent wind tooth followed in the second layer, the wind tooth air passage outlet 12 of the previous wind tooth in the second layer is an effective air outlet of wind tooth toward outside, and the effective air outlet direction is axial; the wind tooth air passage inlet of the previous wind tooth in the first layer is an effective air inlet of wind tooth toward outside, and the effective air inlet direction forms a little crossing angle with the swing of the wind gear; the wind tooth air passage inlet of the previous wind tooth in the second layer is a transitional air inlet of Wind tooth, and the transitional air inlet direction is corresponding to the wind tooth outlet of the adjacent wind tooth followed in the first layer. That is, the gas taken in by the wind tooth air passage inlet 11 of the previous wind tooth in the first layer is processed and then is exhausted into the wind tooth air passage of the wind tooth followed in the second layer to be processed once again before being exhausted outside of the wind gear 3 via the wind tooth air passage outlet in the second layer. The second different point is: the wind tooth bottom is provided with the tooth root support separation plate 13, which supports and connects the roots of wind tooth blades. The third different point is: each of the wind tooth air passages is provided with two lines of pressurization flow deflector 16 therein.

In the embodiment 2, the circulation boosting and ventilating air compressor also adopts the simple pressurization working principle by stamping force. In the working period, the gas taken in by the wind tooth air passage inlet 11 in the first layer and the air inlet 21 at the front edge of wind tooth working surface is decelerated and pressurized before being exhausted into the wind tooth air passage in the second layer to be decelerated and pressurized, and then is exhausted outside of the wind tooth. That is, the gas taken in by the wind teeth is decelerated and pressurized by two times; thereby the pressurization effect is better and high-efficient. Due to the function of the pressurization flow deflector, the gas inside the wind tooth air passage has a larger contact area with the circulation members, thus the gas can absorb more energy and the pressurization effect thereof is better.

In this embodiment 2, the circulation boosting and ventilating air compressor can be used as a high-pressure ducted blower, and can be used as a ventilator directly in case of removing the compressor shell.

Embodiment 3 (please refers to FIGS. 7-10), the circulation boosting and ventilating air compressor in this embodiment 3 is substantially the same as that in the embodiment 2. The first different point is: the wind teeth 7 in the embodiment 3 are formed by overlying five layers of wind tooth blades 9, and the wind tooth air passage is four-layered.

The second different point is: a wind tooth air passage communicating vessel 17 is provided between the wind teeth 7 of the wind gear, and the wind tooth air passage communicating vessel 17 is formed by overlying five layers of a blade 9′ of wind tooth communicating vessel made of sheet iron plate, and the air passage 10′ of wind tooth communicating vessel is four-layered and respectively communicates the wind tooth air passage inlets and outlets of the two wind teeth in front and back; as shown in FIGS. 8 and 10, the air passage inlet and outlet of the wind tooth air passage communicating vessel 17 in the first layer respectively communicate the wind tooth air passage of the previous wind tooth 7 in the first layer and the wind tooth air passage of the wind tooth followed in the second layer; the air passage inlet and outlet of the wind tooth air passage communicating vessel 17 in the second layer respectively communicate the wind tooth air passage of the previous wind tooth in the second layer and the wind tooth air passage of the wind tooth followed in the third layer; the air passage inlet and outlet of the wind tooth air passage communicating vessel 17 in the third layer respectively communicate the wind tooth air passage of the previous wind tooth in the third layer and the wind tooth air passage of the wind tooth followed in the fourth layer; the wind tooth air passage outlet 12 of the previous wind tooth in the fourth layer is an effective air outlet of wind tooth toward outside (which is axial), and the wind tooth air passage inlet 11 of the wind tooth followed in the first layer is an effective air inlet of wind tooth toward outside; each of the adjacent wind teeth and the wind tooth air passage communicating vessel therebetween are arranged and structured in such a manner. The third different point is: the wind tooth top in the embodiment 3 is provided with a leakproof separation plate 15.

In the working period, the gas taken in by the wind tooth air passage inlet 11 of the previous wind tooth in the first layer passes through the wind tooth air passage in the first layer before passing through the air passage of the wind tooth air passage communicating vessel in the first layer, and then the gas enters the wind tooth air passage of the wind tooth followed in the second layer, and then enters the wind tooth air passage of the wind tooth followed in the third layer through the wind tooth air passage communicating vessel 17 followed thereof, and then enters the wind tooth air passage of the wind tooth followed in the fourth layer through the wind tooth air passage communicating vessel 17 followed thereof; and at last the gas is exhausted from the wind tooth air passage outlet of the wind tooth in the fourth layer outside of the wind tooth in an axial direction. That is, the gas is taken in from the air passage inlet of the wind tooth in the first layer, and then is exhausted from the air passage outlet of the wind tooth in the fourth layer outside of the wind tooth; the whole flow is that the gas rotates one circulation along with the rotor, i.e. the gas taken in from the air passage inlet of the wind tooth underwent the flow of being accelerated and pressurized in one circulation, thereby the wind pressure of wind tooth outlet is very high.

Since the wind tooth top is provided with a leakproof separation plate 15, the gas inside the wind tooth air passage can not be exhausted outside of the wind tooth air passage in a radial direction due to the centrifugal force. The gas taken in by the effective air inlet of the wind tooth can totally pass through the wind tooth air passage to be processed and pressurized.

The wind tooth air passage communicating vessel 17 in the embodiment 3 can be made into be empty box-typed, i.e. the whole air passage 10′ of wind tooth communicating vessel is not layered, and the wind tooth air passage inlets and outlets of the two adjacent wind teeth in front and back are corresponding to each other through an inner cavity of the wind tooth air passage communicating vessel 17 (please refer to FIG. 10), so that the gas can be prompted to rotate one circulation inside the wind teeth, so as to be processed and pressurized, thereby obtaining a higher wind pressure. Moreover, such a structure is also applicable for a high-pressure gas compressor.

In this embodiment 2, the circulation boosting and ventilating air compressor can also be made into a high-pressure or super-high-pressure gas compressor in case of adding or not adding the compressor shell.

Embodiment 4 (please refers to FIGS. 11-13), the circulation boosting and ventilating air compressor in this embodiment 4 is substantially the same as that in the embodiment 3. The first different point is: the two wind gears are in series to form the same rotor. The first-stage wind gear and its wind gear plate as well as the second-stage wind gear and its wind gear plate are cylinder-shaped; these two-staged wind gear plates in series to form a uniform cylinder-shaped wind gear plate 4; and these two-staged wind gears in series to form a uniform cylinder-shaped ventilation compressor rotor.

The second different point is: the rotor in this embodiment 4 is provided with a reversing deflector 18 between the two-staged wind gears; and correspondingly, a reversing and deflecting communicating vessel 19 is located between the two-staged wind tooth air passage communicating vessels 17.

In this embodiment 4, the wind tooth air passage inlet 11 of the previous wind tooth of the first-staged wind gear in the first layer communicates to the outside, and the wind tooth air passage outlet. 12 thereof communicates the wind tooth air passage of the adjacent wind tooth followed in the second layer through the air passage of the tooth air passage communicating vessel in the first layer; the wind tooth air passage of the first-staged wind tooth in the second layer communicates to the wind tooth air passage of the followed wind tooth in the third layer through the wind tooth air passage of the wind tooth air passage communicating vessel 17 in the second layer. The wind tooth air passage of the previous wind tooth of the first-staged wind gear in the third layer communicates to the wind tooth air passage of the wind tooth of the first-staged wind gear in the fourth layer through the air passage of the wind tooth air passage communicating vessel 17 in the third layer, and the wind tooth air passage outlet 12 of the wind tooth in the fourth layer communicates the reversing deflector 18 through the reversing and deflecting communicating vessel 19.

The inside air passage of the wind tooth air passage communicating vessel 17 of the second-staged wind gear are also four-layered; the wind tooth air passage inlet 11 of the previous wind tooth of the second-staged wind gear in the first layer communicates to the outlet of the wind tooth reversing deflector 18 through the reversing and deflecting communicating vessel 19, and the wind tooth air passage outlet 12 thereof communicates the wind tooth air passage inlet of the wind tooth followed in the second layer; the wind tooth air passage of the wind tooth in the second layer communicates the wind tooth air passage of the wind tooth followed in the third layer through the wind tooth air passage communicating vessel 17, the wind tooth air passage of the wind tooth in the third layer communicates the wind tooth air passage of the wind tooth followed in the fourth layer through the wind tooth air passage communicating vessel 17, and the wind tooth air passage outlet 12 of the wind tooth in the fourth layer is an effective air outlet of the second-staged wind gear; and the effective air outlet of the wind gear is also a final effective air outlet of the whole rotor.

In this embodiment 4, the circulation boosting and ventilating air compressor adopts the pressurization working principle by both stamping force and rotating force. In the working period, the electric motor drives the rotor rotation; the effective air inlet of the first-staged wind gear takes in gas; the gas inside the wind tooth air passage of the first-staged wind gear flows in a direction contrary to the swing of the wind teeth; the gas inside the wind tooth air passage of the first-staged wind gear is pressurized by means of the stamping force; and the gas is decelerated while flowing. The gas flows into the wind tooth reversing deflector 18 after flowing out the wind tooth air passage of the wind tooth of the first-staged wind gear in the fourth layer, that is, the gas is reversed to flow into the wind tooth air passage of the wind tooth of the second-staged wind gear in the first layer; at this time, the gas flow is accelerated in virtue of the rotating force, and then the gas passes through the wind tooth air passages of the wind teeth of the second-staged wind gear in the second, third and fourth layers through the acceleration and pressurization of the wind tooth air passage communicating vessel 17, and then the gas flows out the second-staged wind gear via the wind tooth air passage outlet 12 of the wind tooth in the fourth layer, i.e. finally flowing out the ventilation compressor rotor.

In the whole working process, the gas rushes into the first-staged wind gear via the effective air inlet of the first-staged wind gear, and then is exhausted outside of the second-staged wind gear via the wind tooth air passage outlet of the second-staged wind gear in the fourth layer. The gas inside ventilation compressor rotor undergoes the flow of being pressurized in two circulations, thereby the wind pressure thereof is very high.

In this embodiment 4, the circulation boosting and ventilating air compressor is not provided with a special extra-thick compressor shell, but is merely provided with a simple and portable rotor cover to ensure the acquisition of high-pressure gas; the acquired high-pressure gas is then exhausted for use by a rectifier at the outlet of the compressor body.

This embodiment 4 is adapted to be made into a super-high-pressure gas compressor for use.

Embodiment 5 (please refers to FIG. 14), the circulation boosting and ventilating air compressor in this embodiment is substantially the same as that in the embodiment 4. The differences are: the rotor is provided with a static reversing deflector 20 at the outlet of the first-staged wind gear; after the gas taken in and processed by the first-staged wind gear is exhausted outside of the wind gear, the gas is reversed by the static reversing deflector to flow into the second-staged wind gear; the gas is processed by the second-staged wind gear in virtue of the rotating force, and is exhausted outside of the rotor via the wind tooth air passage outlet of the wind tooth of the second-staged wind gear in the fourth layer; the gas enters the rotor via the wind tooth air passage inlet of the wind tooth of the first-staged wind gear in the first layer, and can obtain a very high wind pressure after undergoing the flow of being processed and pressurized in two circulations.

This embodiment 5 is adapted to be made into a super-high-pressure gas compressor for use.

Embodiment 6 (please refers to FIG. 15), the circulation boosting and ventilating air compressor in this embodiment is substantially the same as that in the embodiment 4. The differences are: the drive shaft 4 in this embodiment is not the same spin axis; the first-staged wind gear and the second-staged wind gear are driven to rotate respectively by two concentric axes which rotate in the opposite direction; the first-staged wind gear rotates in a direction contrary to the flow direction of the gas inside the wind tooth air passage thereof; the second-staged wind gear rotates in a direction same as the flow direction of the gas inside the wind tooth air passage thereof by means of the stamping force, and the gas is pressurized mainly by means of the rotating force.

In the working period, the gas inside the air passage of the first-staged wind gear has a flow rate lower and lower, but it can gradually be accelerated directly in virtue of the rotating force after flowing into the wind tooth air passage of the second-staged wind gear, and finally it is exhausted outside of the wind gear via the effective wind tooth air passage outlet of the second-staged wind gear. The gas enters the rotor via the effective wind tooth air passage inlet of the first-staged wind gear, and finally is output by the compressor body converging the rectifying devices for use after undergoing the flow of being processed and pressurized in two circulations.

This embodiment 6 is adapted to be made into a high-pressure or super-high-pressure gas compressor for use.

Embodiment 7 (please refers to FIG. 16), the circulation boosting and ventilating air compressor in this embodiment is substantially the same as that in the embodiment 3. The differences are: the circulation boosting and ventilating air compressor in this embodiment has two wind gears in series for use; the gas rotates two circulations to be pressurized; and a starting fan 23 is provided in a front end of the rotor. In the working period, the fan supplies wind directly for the wind tooth air passage of the first-staged wind gear; since the fan and the two-staged wind gears are driven to rotate by the same drive shaft, the gas inside the rotor rotates and flows from beginning to end along with the swing of the same drive shaft, thus absorbing energy continually to increase the pressure thereof. Obviously, the circulation boosting and ventilating air compressor with such a structural manner adopts the simple rotating force to increase the pressure.

This embodiment 7 is adapted to be made into a super-high-pressure gas compressor for use.

Embodiment 8 (please refers to FIG. 16), the circulation boosting and ventilating air compressor in this embodiment is the same as that in the embodiment 7. The differences are: the rotor in this embodiment is not provided with a fan in the front end thereof; the wind tooth air passage inlet direction of the rotor is the same as the swing of the rotor; when the rotor rotates in a high speed, a negative pressure is produced at the effective air inlet in the front side of the first-stage wind gear, which draws the gas directly into the wind tooth air passage to be accelerated and pressurized continually, so that the gas can obtain an extra-high wind pressure when reaching the wind tooth air passage outlet of the rotor.

The circulation boosting and ventilating air compressor in this embodiment 8 is adapted to be adopted by the engines of various vehicles, ships and aircrafts.
